hey girls! I am in need of help because I am about to lose my mind from worry. My last period was September 22, 2009 and my boyfriend and I had our brief first time on October 27, 2009. I have always been regular but I have not had a period since September. I keep thinking I could be pregnant but neither my boyfriend nor I think I could be because he pulled out and it was all over the sheets (which we quickly stripped and washed.) We went slow so that we could control how excited we got and maybe some pre-cum came out but not much at all. I have been worrying ever since and I've taken 3 hpt's and they've all come out negative. I feel like my period is here but nothing is coming out. I've been getting a little cramping, no spotting, no sore breasts, no sickness whatsoever, or anything. I have been under a lot of stress lately with this and other things that are going on in my life, but I'm scared out of my mind. What's wrong with me???
